Abstract: Flow of a viscous incompressible Newtonian fluid in a cylindrical compliant tube is examined numerically. The proposed model solves the coupled flow-structure problem by recasting the governing flow equations into the standard Poiseuille form. The interaction between the fluid flow and the dynamics of the structure is accounted for by an additional induced force in the momentum equation and a source term in the continuity equation. The numerical results show that the former affects the dynamics of the flow, whereas the latter controls the shape of the structure.
